Every man must do two things alone he must do his own believing and his own dying.

Look at the sky. We are not alone. The whole universe is friendly to us and conspires only to give the best to those who dream and work.

Even in the presence of others he was completely alone.

Always give a word or sign of salute when meeting or passing a friend, or even a stranger, if in a lonely place.

What a lovely surprise to finally discover how unlonely being alone can be.

I never said, 'I want to be alone.' I only said, 'I want to be left alone.' There is all the difference.

All men's miseries derive from not being able to sit in a quiet room alone.

I don't want to be alone, I want to be left alone.

As I get older I'm more and more comfortable being alone.

The capacity for not feeling lonely can carry a very real price, that of feeling nothing at all.
